I have 2011 e-tect on 25 ft. pontoon. It runs great, except if I run at 2000 rpms or less. It will stall after 10-15 minutes. I pump the bulb and it runs again. The dealer has replaced the fuel line and bulb, but it does the same thing. The dealer thinks it may be the take up fuel pump at $700 or more, with no way to test other than ok installing the fuel pump. Is there any possible other solution? or any way to test to see if a new pump is needed without just installing the pump? Also the primer bulb is never hard, it's just half way firm,but never flat. Should the bulb be hard, the dealer says newer motors bulb don't pump up to hard as older motors did. Is that normal with primer bulbs now?

Your dealer tech should know how to connect a pressure gauge to the high pressure pump and lift pump while a vacuum gauge and a piece of clear fuel line is temporarily connected to the lift pump inlet fitting. Running the boat at all rpms and recording the readings will narrow down if it is a fuel problem. Monitoring and using the flight recorder function with a laptop will show if there are any other anomalies in the engine.
